Description
Powers should be doable exactly using confluent hypergeometric functions. See, e.g., the final case analyzed at https://mathworld.wolfram.com/GaussianIntegral.html.
It may also be possible to return the exact answer for log: https://math.stackexchange.com/questions/1359584/an-integral-involving-a-gaussian-and-a-logarithm

Research direction
Start by reviewing the Gaussian Integral and Math StackExchange references linked in the issue, then inspect the package's existing power and log entry points. Determine which powers require exact confluent-hypergeometric forms and define tests that distinguish exact results from the current approximations; the issue does not name files or existing tests.
